I have an ancient Crusader kiln. Firing to cone 6 usually takes about 8
hours. The recent firing took 16 hours. The elements appear to heat
normally. Any ideas as to what could be causing the long firing before
reaching cone 6? Thanks.

Dear Bob,
You need new elements. You can get them from Euclid's. Just do a web
search--I don't know their address. Probably euclids.com or something
similar.
Another cause of slow firing can be an inadequate power supply, but since
the kiln is old and it worked all right before, it's most likely the
elements. They loose their oomph after awhile.
Best wishes and Merry Christmas

A rule of thumb:
Firing time suddenly becomes longer = element or switch failure
Firing time gradually becomes longer = worn elements
Since your elements all light up, and it sounds like firing time suddenly
became longer, perhaps the problem is a defective switch that stays on low
instead of high. (I don't know what type of switches your kiln has.)
